How to distinguish between surface cracks, deep cracks and penetrating cracks?

A surface crack refers to a surface crack, a deep crack refers to a deep crack, and a penetrating crack refers to an object that is completely cracked without being broken. The meanings of these three words are different, so it is relatively simple to explain.

Generally, structural cracks are divided into surface cracks, deep cracks and penetrating cracks.

The main manifestations of surface cracks are temperature cracks and dry shrinkage cracks on the surface of components, which are generally not harmful, but affect the appearance quality, belong to the category of quality defects, and need to be treated.

Deep cracks are the further development of surface cracks, due to the change of external conditions, the cracks have been extended to the inside of the construction, so that the component section is weakened, can not work at the same time, the structural force, durability is affected, must be treated.

Penetration crack is the further development of deep crack, due to the further deterioration of external conditions resulting in the entire section of the component crack through, the component completely loses the bearing capacity, which will lead to quality accidents or safety accidents, and immediate measures must be taken.

The surface crack is only a shallow crack on the surface, it will not be very deep, and it will not be particularly wide, the depth crack should be relatively wide, and we can use the object to test it downward, we can know that it is not only deeper, but also such a deep crack will be relatively wide, through the crack is that the crack has penetrated the entire wall, we are easier to judge at this time, because we can see the bright light on the opposite side.

The cracks in large-volume mixed concrete are divided into three types: surface cracks, deep cracks and penetrating cracks according to different depths

1. Surface cracks are mainly temperature cracks, which are generally less harmful but affect the appearance quality.

2. Deep cracks partially cut off the structural section, which has a certain hazard to the durability of the structure.

3. Penetrating cracks are developed from cracks on the surface of concrete to deep cracks, and finally form penetrating cracks; It cuts off the cross-section of the structure, which may destroy the integrity and stability of the structure, and its harm is more serious.

What is the difference between surface cracks, deep cracks and penetrating cracks? Surface cracks are a layer of surface cracks, if the depth of the surface cracks, how to distinguish between deep cracks and through cracks? A surface crack is a layer of surface, and if the depth is a crack in a very deep place.

The deeper the deeper, the deeper.

Of course, it is a big distinction, because surface cracks are only very shallow depth, cracks are very deep, and penetrating cracks are common, and they each have their own shape.

Summary. The difference between a penetrating crack and a penetrating crack is that one is a vertical penetration and the other is a longitudinal penetration

Wait a minute, kiss and wait, I'm answering for you.

The difference between a penetrating crack and a penetrating crack is that it is a vertical penetration, and a longitudinal penetration, which refers to, and the vertical depth (which proves that it has been broken) - penetration, which refers to; Longitudinal (striated) refers to length.

Kiss, this is a through crack

Is there a problem with this crack in the rough house? Is it normal?

Dear, it's normal to have cracks in the embryonic room, but this crack of yours is a little too long and big.

It is best to check the development of the crack to see if he is able to penetrate the funnel. You can sprinkle some water on the cracks, and then I'll go downstairs to see if the roof design is dripping or seeping. Mausoleum infiltration.

If it can seep water, then you must patch the cracks, you can use grout to try Oh I haven't bought it yet, so it's better not to buy it, right?

Dear, yes, it's a bit of a problem to say that it belongs to the embryo room, maybe the workmanship is not done well, is there a problem with this.

Kiss, I can't see this ** clearly.

What's wrong with this **.

Kiss, the following related ** is a normal phenomenon, this does not need something.

The above words are quite clear.
